GAS-STOVE.

Application led March 30, 1917.

vention is to provide an improved gas heater or stove having a heating drum, which when necessity requires may be used to burn wood for heating purposes.

Another obj ect of the invention is to provide an improved gas heater in the upper portion of which a heating drum is formed, means being provided for establishing a communication between the heater and the drum whereby the products of combustion may pass through the drum in order to heat the same, suitable draft devicesand regulators being provided for controlling the communication between the heater and the drum.

A further object of the invention resides in the provision of an improved gas heater of the class described which will be characterized by advantages of simplicity, durability, efficiency in operation and economy in manufacture and maintenance.

With these and other advantages in view which will become apparent as the description proceeds, theinvention resides in the construction, combination and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which like characters of reference indicate like parts throughout the several figures of which,

Figure 1 represents a view in perspective of a stove constructed according to my invention. e

Fig. 2 represents a Vview in section taken transversely through the stove on the plane indicatedby the line 2-2 of Fig. 1, and.

Fig. 3 represents a rear elevational view of the upper portion of the stove, a portion of the back of the stove being broken away to show the damper.

Referring more particularly to the drawing, 5 indicates the back of the stove, 6 the front thereof and 7 the sides. The top portion of the stove is preferably rounded or oval in shape as shown in the drawing. The

.upper portion forms or comprises a hollow drum 8 separated from the lower portion Specification of Letters Patent.

of the stove through the medium of the hori- Zontal partition 9.

The front wall of the stove is provided with a large opening 10 at the back of which occurs a curved reector 11 of suitable form. The lower end of the reflector engages against the lower portion of the front wall as shown, and the upper edge of the reflector terminates short of an inclined partition 12, an opening thus being defined between the partition and reflector. The compartment 14 thus defined in the rear of the reiiector communicates with the compartnient defined in front of the reflectorthrough the opening 13, and communicates with the air through perforations 15 provided in the side walls 7 and through an opening 16 defined at the lower portion of compartment 14 by reason of the fact that the rear wall 5 terminates short of the lower ends of the side walls 7. In the upper portion of the compartment 17 defined in front of reector 11, and adjacent the upper edge of the reflector is arranged a gas burner 18 provided with a suitable cock or valve 19 for regulating the flow of gas through the burner. This burner is connected by means of a flexible pipe (not shown), or in some other suitable manner with a source of gas supply. At the upper portion of the coinpartment 17 the side walls 7` of the stove are perforated as at 20 for the admission of air to the compartment. A shield 21 of suitable form is arranged in front of the burner 18 at the upper end of the opening 10 in the front wall of the stove.

The inclined partition 12 has its forward edge scalloped or provided with a plurality of recesses as at 22 whereby communication is established between the upper end or portion of the compartment 17 and the conipartment 23 formed between the partitions 9 and 12. The forward edge of the partition 12 is preferably bent upwardly out of Contact with the front wall of the stove. A` pipe 24 arranged on the rear side of the stove, establishes a passage between the compartment 23 and the drum 8, the rear wall of the stove being provided with a perforation or opening 25 at the lower end of the pipe and with a semi-circular opening 26 at the upper end of the pipe. A semi-circular damper plate 27 arranged on a rod 28 controls the passage through the opening 26. rIbis rod extends rearwardly through the wall of pipe 24 and is provided with a suitable key 29 whereby it may be adyusted to various positions.

Ordinarily the stove will be heated by 1The products of combustion will pass upwardly through the recesses or scallops 22 through the compartment 23, thus heating the front, end, and side walls of the stove adjacent the compartment, through the pipe 24 and into and through the drum 8, heating the latter, and then passing off through a suitable pipe 30 with which the stove is equipped. The passage of products of combustion through the pipe 24, will of course, be regulated by the damper 27, and in case the drum is to be used as a wood heater the damper is moved to entirely cover the openingV 26 whereby to cut of passage of air from the pipe 24. The drum 8 has its upper wall provided with an opening equipped with a removable cover 31, whereby access to the drum, for placing wood therein and for removing ashes may be had. One end of the drum, prefer-ably the end removed from that end adjacent which the pipe 30 is positioned, is provided with an opening controlled by suitable draft regulator 32, so that the proper amount of air for aiding in the combustion of the wood may be admitted to the drum. The damper or'draft regulator 32 includes a disk 33 mounted on a threaded rod 34,1 which turns through a threaded boss 35 formed on a web 36 which extends across the opening in the end wall of the drum. The outer end of rod 34 is provided with a suitable handle 37 whereby the rod may be readily turned. If the gas pressure is low, a wood tire may be built in the drum to augment the elifects of the gas in properly heating the room in which the stove may be placed, and in such instances the damper 27 may be turned to uncover the opening 26 to sufficiently allow the products of combustion from the burner 18 to pass ott. It will be noted that the opening 26 occurs adjacent the top of the drum, so that the products of combustion from the burner will pass across the upper portion of the drum so as not to interfere with the proper combustion of the wood. When no iire is burning in the drum, it is preferable to open the damper 2'7 to its fullest extent to allow a relatively great volume of the products of combustion to pass into the drum so as to virtually lill the same and keep it in a heated condition. The draft regulator 33 will, of course, be kept closed when no wood fire is burning in the drum.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement oi' parts thereof, as do not depart from the spirit of the invention and the scope of the appended claims.
